at_backupkey_flutter 4.0.11 at_backupkey_flutter: ^4.0.11 copied to clipboard
A Flutter plugin project for saving the backup key of any atSign that is being onboarded with atPlatform apps. The backup key can be used to authenticate in other atPlatform apps.
The at_backupkey_flutter package provides the functionality to take backup of secret keys of an onboarded atSign.
This open source package is written in Dart, supports Flutter and follows the atPlatform's decentralized, edge computing model with the following features:
- Cryptographic control of data access through personal data stores
- No application backend needed
- End to end encryption where only the data owner has the keys
- Private and surveillance free connectivity
We call giving people control of access to their data “flipping the internet” and you can learn more about how it works by reading this overview.

1. Clone it from GitHub #
Feel free to fork a copy of the source from the GitHub repo. The example code contained there demonstrates the usage of this package.
$ git clone https://github.com/atsign-foundation/at_widgets
2. Manually add the package to a project #
Instructions on how to manually add this package to you project can be found on pub.dev here.
How it works #
Secret keys are generated for an atSign during onboarding flow of atProtocol. This package helps to add those keys in '.atKeys' file. This file can then be saved in the local filesystem or iCloud/Gdrive.
The following platform specific setups are required:
Add android:exported = "true" to activity
<activity android:name=".MainActivity" android:exported="true" ...>
Add the following permissions to AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />
Also, the Android version support in app/build.gradle
compileSdkVersion 29 minSdkVersion 24 targetSdkVersion 29
